This may be obvious, but now that Inquisitor has been bought by Yahoo, the instant display of web sites matching your search terms only works if Yahoo is set as the preferred Search Engine in the Inquisitor (Search) Preferences in Safari. It's set this way by default (so Inquisitor works out of the box), but if you prefer to use Google for your searches, you'll lose the main benefit of installing Inquisitor.

From the website you linked to: "Using both Glims and Saft on the same browser could have unexpected results."

And out goes Glim. I have looked at it before, and thought it to be nice, but Saft is an excellent helper for Safari. Expecially if you want Safari to have some nice features like FireFox has/can have, via extensions.

And instantly. Inquisitor loses ALL value. If someone prefers something other than Yahoo, MAKE YAHOO BETTER, don't force them to sacrifice functionality and suffer with a search engine they don't prefer.

I can accept that's is a bug due to a change in Google. But this doesn't explain why results from Amazon, Wikipedia and other engines aren't displayed no more. And it doesn't explain why, when choosing Yahoo as first engine, the "Google's bug" is still here (No results are displayed since two or three days).
